I was on a business trip to Seoul, but also had some time for sightseeing. I stayed 3 nights at this hotel. This is clearly a reformed love hotel. The decor is quite pink and there is a bit too much neon in the hallways. The fact that it used to be a love hotel at one time does not mean it is bad, but there are some things to watch out for.
1) No workspace. There is really no space in the room to work or sit at a desk. The wired internet is not anywhere near where it would be convenient to work. So, try not to plan on doing anything computer related in the room.
2) the bed is like stone. The bed is incredibly hard, which is not all that bad for me, but some people might hate it. It is actually harder than my bed in Japan (which is a futon on the floor).
3) Shower has no curtain. A big indicator of the love hotel status is the bathroom, which is quite strange. There is no curtain or separator for the shower, so your water will go everywhere. There was also a little pink light above the bath for that extra romance.
4) The hill. It is at the top of a hill, but it is not a bad climb.
5) The cleaning seemed to get worse each day. I stayed only 3 nights and each day they seemed to do one less job. By the third day staff did not replace the amenities, did not provide new towels, and did not collect the garbage.

There are some good things too:
1) The staff. Very friendly and helpful. They provide a safety box on the first floor if you need it and they also gave me a power adapter since mine didn't work (they ask for a small deposit). The staff arranged for my DMZ tour and I was picked up from the hotel for the tour.
2) Location of the place (except for the hill) is great. It is well placed within 20 minutes of two shopping areas, 1 traditional market, and 1 modern shopping district. It is not far to city hall area and other attractions walking or by subway.
3) The price was good. There might be better places for the same or similar price, however. I had a tough time booking other places because it was peak travel season and a weekend.

Tip: There are quite a few nice cafe's nearby on the way down the hill or just left at Woori bank around the corner. They serve nice variety of organic herbal and other teas/coffees.

My friend and I returned from Seoul last night after staying at the Hill House for two nights.

Our rooms were spacious and clean, with comfortable beds and very large, wall-mounted televisions with three or four channels of English programming. The bathrooms were also fine, with more products available than most other hotels I'd stayed at (including cologne and hair gel, for example).

The location was GREAT, being a 4-minute walk to the well-located Hoehyeon station, an 8-minute walk to Dongdaemun market, and a 10-minute subway (or 15-minute taxi) ride to Itaewan.

The hotel service was friendly and efficient, and the breakfast - although minimal with toast, fried eggs, coffee and juice - was most welcome after a night of drinking. Being a big guy, I doubled up on the food, as did some of the other guests. Free bottled of water in the mini-fridge below the TV also came in handy, although there are three convenience stores within a 2-3 minute walk from the hotel.

There were a few minor flaws, with perhaps the biggest being the heavily soiled carpeting on the stairs and 2nd floor. My room also lacked clothing drawers and the hotel didn't have an iron. There were also no light switches in the rooms. Once you put your room key in the slot, it activates all the lights and electricity. Take it out and everything goes off. So, for people who like to read by a lamplight alone or watch TV in the dark, those aren't options. To me, anyway, these drawbacks proved to be small inconveniences in an otherwise great experience!
